CesiumJS Imagery Layers
CesiumJS v1.143 -- Imagery providers supply raster tile data rendered on the Globe or draped over a Cesium3DTileset. The three core abstractions are ImageryProvider (fetches tiles), ImageryLayer (display settings), and ImageryLayerCollection (ordered stack on the globe).
ImageryProvider (abstract -- fetches tile images)
-> ImageryLayer (wraps one provider; alpha, brightness, split, etc.)
-> ImageryLayerCollection (ordered stack; index 0 = base layer)
-> Globe / Cesium3DTileset
Layers render bottom-to-top. Index 0 is the base layer, stretched to fill the globe even if its rectangle does not cover the entire world.
